"Our managing partner was actually mowing his lawn when he was alerted,” company spokesman Travis Doster told FOX 47. "He immediately rushed to the restaurant, met with the employee who posted this disgusting tweet and she was terminated."

Olson didn't return a request for comment, but reportedly posted an apology on Facebook, according to the station.

"I wrote hurtful, inconsiderate, insensitive and careless words and I understand the amount of people I have offended by that. There are no excuses for what I have done. I sincerely, from the bottom of my heart, apologize to everyone for my momentary lack of judgment. I want you all to know that I do not actually feel this way."
